you may have seen in our other tests. It also features a <a href=\"https:\/\/www.tegiwaimports.com\/tegiwa-exhaust-manifold-header-honda-k-swap.html\"><strong>Tegiwa K-swap manifold<\/strong><\/a>; this has relatively large runners and is a 4-1 style manifold with a megaphone 3\u201d exit. This then mates to a <a href=\"https:\/\/www.tegiwaimports.com\/greddy-3-catback-exhaust-system-ss-supreme-sp-honda-civic-ek-3dr-96-00.html\"><strong>3\u201d GReddy cat-back system<\/strong><\/a> from there.

Plus, we needed to ensure the engine was still as healthy as it was previously after a minor gearing issue at Time Attack. So, after an initial run we saw 249.2hp. Eagle eyed readers might notice that WHP (wheel horsepower) is lower than it was before, this is because the car now has bigger, wider and stickier tyres on it than it did at the time of the OG cam test! Good job we ran it up to check, eh!?<\/p>\n<p><a href=\"https:\/\/www.tegiwaimports.com\/blog\/wp-content\/uploads\/2021\/06\/Skunk2-DIC-Dyno.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-large wp-image-4808\" src=\"https:\/\/www.tegiwaimports.com\/blog\/wp-content\/uploads\/2021\/06\/Skunk2-DIC-Dyno-1024x979.jpg\" alt=\"\" width=\"640\" height=\"612\" srcset=\"https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/06\/Skunk2-DIC-Dyno-1024x979.jpg 1024w, https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/06\/Skunk2-DIC-Dyno-300x287.jpg 300w, https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/06\/Skunk2-DIC-Dyno-768x734.jpg 768w, https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/06\/Skunk2-DIC-Dyno-640x612.jpg 640w, https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/06\/Skunk2-DIC-Dyno-1920x1836.jpg 1920w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/a><\/p>\n<p>So, the Skunk2 drop in cam does, as we see before, strong, low cam performance and hits VTEC at 5500 with the rev limit set at 8600rpm. The reason for this is due to running stock valve. Of course, we could take a risk and run more RPM on the stock valve spring but with DIC, Jesse tends to air on the side of caution. I guess we could even say that upgraded valve springs on the DIC\u2019s could be a potential benefit to allow a higher RPM to be used safely. With the \u201cbefore\u201d test complete, this essentially backs up the results we saw last time with the <a href=\"https:\/\/www.tegiwaimports.com\/hondata-k-pro-ecu-honda-civic-type-r-ep3-k20a2-uk-01-06.html\"><strong>Hondata K-Pro.<\/strong><\/a><\/p>\n<p><strong>249.2hp and 156.6lbft<\/strong><\/p>\n<p>Naturally, we had the guys at <a href=\"https:\/\/motion-motorsport.co.uk\/\"><strong>Motion Motorsport<\/strong><\/a> install our springs, retainers, and camshafts for us. They installed the parts with the head in situ, saving a good chunk of labour costs. Motion suggests that this kind of job would usually cost the customer around \u00a3180 more than it would to have this setup fitted over the DIC\u2019s.<\/p>\n<div id='gallery-3' class='gallery galleryid-4794 gallery-columns-3 gallery-size-thumbnail'><figure class='gallery-item'>\n\t\t\t<div class='gallery-icon landscape'>\n\t\t\t\t<a href='https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/06\/Skunk2-UltraCams-8.jpg'><img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/06\/Skunk2-UltraCams-8-150x150.jpg\" class=\"attachment-thumbnail size-thumbnail\" alt=\"\" srcset=\"https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/06\/Skunk2-UltraCams-8-150x150.jpg 150w, https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/06\/Skunk2-UltraCams-8-197x197.jpg 197w, https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/06\/Skunk2-UltraCams-8-245x245.jpg 245w\" sizes=\"auto, (max-width: 150px) 100vw, 150px\" \/><\/a>\n\t\t\t<\/div><\/figure><figure class='gallery-item'>\n\t\t\t<div class='gallery-icon landscape'>\n\t\t\t\t<a href='https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/06\/Skunk2-UltraCams-10.jpg'><img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/06\/Skunk2-UltraCams-10-150x150.jpg\" class=\"attachment-thumbnail size-thumbnail\" alt=\"\" srcset=\"https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/06\/Skunk2-UltraCams-10-150x150.jpg 150w, https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/06\/Skunk2-UltraCams-10-197x197.jpg 197w, https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/06\/Skunk2-UltraCams-10-245x245.jpg 245w\" sizes=\"auto, (max-width: 150px) 100vw, 150px\" \/><\/a>\n\t\t\t<\/div><\/figure><figure class='gallery-item'>\n\t\t\t<div class='gallery-icon landscape'>\n\t\t\t\t<a href='https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/06\/Skunk2-UltraCams-9.jpg'><img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/06\/Skunk2-UltraCams-9-150x150.jpg\" class=\"attachment-thumbnail size-thumbnail\" alt=\"\" srcset=\"https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/06\/Skunk2-UltraCams-9-150x150.jpg 150w, https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/06\/Skunk2-UltraCams-9-197x197.jpg 197w, https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/06\/Skunk2-UltraCams-9-245x245.jpg 245w\" sizes=\"auto, (max-width: 150px) 100vw, 150px\" \/><\/a>\n\t\t\t<\/div><\/figure>\n\t\t<\/div>\n\n<h4><strong>Onto the good stuff<\/strong><\/h4>\n<p>Now it\u2019s time for the exciting part, <a href=\"https:\/\/www.tegiwaimports.com\/skunk2-k-series-ultra-1-camshafts-cams.html\"><strong>Skunk2 Racing Ultra 1\u2019s<\/strong><\/a>!<\/p>\n<ul class=\"td-arrow-list\">\n<li><a href=\"https:\/\/www.tegiwaimports.com\/skunk2-k-series-ultra-1-camshafts-cams.html\"><strong>Skunk2 Racing Ultra 1 Camshafts<\/strong><\/a> &#8211; \u00a31,130.16<\/li>\n<li><a href=\"https:\/\/www.tegiwaimports.com\/skunk2-pro-series-xp-valve-springs-honda-k-series-i-vtec.html\"><strong>Skunk2 Racing Pro Series XP Valve Springs<\/strong><\/a> &#8211; \u00a3384.02<\/li>\n<li><a href=\"https:\/\/www.tegiwaimports.com\/skunk2-titanium-retainers-honda-k-series.html\"><strong>Skunk2 Racing Titanium Retainers<\/strong><\/a> &#8211; \u00a3223.82<\/li>\n<\/ul>\n<p>Low cam performance seems to be stepped up again over the DIC\u2019s, potentially a little weaker sub 3500rpm but a good bit stronger in the 5000-6000 area. The Ultra 1\u2019s make a good 7lbft more torque at 5500rpm which is where the DICs got criticised in the last test. The low cams hold good power up to 6500rpm on this setup with a seamless VTEC crossover. This won&#8217;t be to everybody\u2019s taste, having a seamless crossover, but technically making the car faster.<\/p>\n<p>We can see the high cam comes into its own after 7000rpm with peak torque of 159lbft at 7800rpm and holds a consistent 6-7hp over the drop in cam in this area. Here is where the value of the valve spring upgrade comes in. Holding a strong power curve from our old rev limit of 8600 up to the new 9000rpm limit. The car makes 260hp, but power is still climbing so Jesse suspects it\u2019ll go another 3-4hp or so if we had an oil pump that could sustain prolonged high RPM use and a slightly higher rev limit.<\/p>\n<p><a href=\"https:\/\/www.tegiwaimports.com\/blog\/wp-content\/uploads\/2021\/06\/Skunk2-Ultra1-Dyno.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-large wp-image-4809\" src=\"https:\/\/www.tegiwaimports.com\/blog\/wp-content\/uploads\/2021\/06\/Skunk2-Ultra1-Dyno-1024x979.jpg\" alt=\"\" width=\"640\" height=\"612\" srcset=\"https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/06\/Skunk2-Ultra1-Dyno-1024x979.jpg 1024w, https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/06\/Skunk2-Ultra1-Dyno-300x287.jpg 300w, https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/06\/Skunk2-Ultra1-Dyno-768x734.jpg 768w, https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/06\/Skunk2-Ultra1-Dyno-640x612.jpg 640w, https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/06\/Skunk2-Ultra1-Dyno-1920x1836.jpg 1920w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/a><\/p>\n<h5><strong>260.4hp and 159lbft<\/strong><\/h5>\n<p>260+ horsepower on this dyno is a good result. Bear in mind this setup on stock cams only just scraped 240hp. That\u2019s an increase of 20+ horsepower (with oil pump) which on an already, very good naturally aspirated, 2 litre engine is very impressive. It proves that Skunk2 Racing have come good on their quote of midrange and top end gains, with the gains over DIC coming in mainly between 5000-6000rpm and then 7000rpm upwards.<\/p>\n<p><a href=\"https:\/\/www.tegiwaimports.com\/blog\/wp-content\/uploads\/2021\/09\/Skunk2-UltraCams-11.jpg\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-4901 size-large\" src=\"https:\/\/www.tegiwaimports.com\/blog\/wp-content\/uploads\/2021\/09\/Skunk2-UltraCams-11-1024x1024.jpg\" alt=\"\" width=\"640\" height=\"640\" srcset=\"https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/09\/Skunk2-UltraCams-11-1024x1024.jpg 1024w, https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/09\/Skunk2-UltraCams-11-150x150.jpg 150w, https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/09\/Skunk2-UltraCams-11-300x300.jpg 300w, https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/09\/Skunk2-UltraCams-11-768x768.jpg 768w, https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/09\/Skunk2-UltraCams-11-640x640.jpg 640w, https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/09\/Skunk2-UltraCams-11-197x197.jpg 197w, https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/09\/Skunk2-UltraCams-11-245x245.jpg 245w, https:\/\/www.tegiwa.com\/blog\/wp-content\/uploads\/2021\/09\/Skunk2-UltraCams-11.jpg 1250w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/a><\/p>\n<p>As always, a big shout out to the master himself, <a href=\"https:\/\/www.facebook.com\/JCal-Ecu-Calibration-189444011623395\"><strong>Jesse Halford<\/strong><\/a>, for carrying out the test and documenting the results for us.
